Reed Relays: 9201-12-20TR Application Field and Working Principle

Reed relays are electronic components that are composed of a coil and a reed switch. The reed switch is made from two ferromagnetic contacts that are enclosed in a fragile glass tube. When a magnetic field is present, the contacts close and the reed switch turns on. The current that flows through the wire then energizes the coil, which in turn produces an electromagnetic field that opens the contacts again. This process will then create a repetitive cycle that allows the reed relay to be turned on and off repeatedly.

Reed relays have a variety of uses, but are mainly used for feedback, feedback control, and timer circuits. They are also often used to switch signals between two systems, and to activate a certain action once a set point is reached, such as in thermostats.

The 9201-12-20TR is a reed relay manufactured by the company Potter & Brumfield. This reed relay can handle a maximum current of 10 amperes with a voltage rating of up to 110 volts. It is composed of a coil and a reed switch, and is typically used to control or switch the on and off states of electrical circuits.

The working principle of a 9201-12-20TR reed relay is relatively simple. When a current flows through the wire, it energizes the coil and produces an electromagnetic field. This magnetic field will then move the reed switch, which is encapsulated in the glass tube. Once this switch is open, the contacts of the reed switch will close, allowing electrical current to flow from one point to another. When the current is stopped, the contacts will open again, thus preventing any further current from flowing.

The 9201-12-20TR reed relay is often used in many types of circuits. It can be used in feedback and control systems, such as those used in temperature control, sound detection, and security circuits. It is also used in timer circuits, where it acts as an activator for a certain action. Additionally, it can be used to switch signals between two systems.

In conclusion, the 9201-12-20TR reed relay is an efficient, dependable, and versatile component. It can handle currents of up to 10 amperes, and has a voltage rating of up to 110 volts. Its uses include feedback and control systems, timer circuits, signal switching, and various other applications. It is composed of a coil and reed switch that work together in a repeating cycle, allowing it to be turned on and off repeatedly.
